Title: Trouble precognition system for power system
Inventor: KANAI MINORU
IPC: H02H3/00
Filed: 1988-10-19
Abstract: PURPOSE:To reduce insulation deterioration in a power system and influence of noise to the detection of its zone and to detect with high sensitivity by dividing the system into a plurality of zones, providing zero-phase current sensors in the boundaries of the zones, and determining the insulation deterioration of the zero on the basis of its general evaluation. CONSTITUTION:When insulation deterioration occurs in a feeder II, ground charging currents IC1, IC3 of hot-line feeders I, III flow to a deterioration point F through a feeder 3. A current IN also flows to the point F through an equivalent resistor 21. On the other hand, charging currents IC2' and IC2'' also flow reversibly through the point F via the feeder II itself. As a result, zero-phase currents detected by the zero-phase current sensors of II-b and II-c become reverse phase, and the currents except the former become in phase. Accordingly, the presence of the deterioration point in the zone interposed between the zero- phase current sensors having the reverse phase can be detected.

Filed: 1985-11-22
Abstract: PURPOSE:To effect the catalytic reaction of liquid fuel efficiently and burn the liquid fuel safely and economically without producing any pollutant by a method wherein the liquid fuel is oxidized and decomposed by catalyzing it under a temperature lower than a specified temperature in the presence of a catalyst while the decomposed product is burnt in gas phase at the downstream of the catalyst. CONSTITUTION:The introducing unit of combustion air is constituted of a liquid fuel introducing tube 1 and a combustion air introducing tube 2. Liquid fuel is evaporated when it comes into contact with a heated metallic wall surface 6. A decomposing reaction and combustion unit is provided with a ceramics form 10 and a honeycomb catalyst 11. The flow rate of fuel for a catalyst layer is controlled so as to be 1-6Kcal/cm<2>H while the temperature of the catalyst layer is set below 1,200 deg.C and especially in the range of 500-1,200 deg.C. The decomposing and oxidizing reaction of the fuel are caused near the surface of the catalyst layer while the gas phase combustion reaction is caused in the downstream of the position of the decomposing and oxidizing reaction. The evolving quantity of NOX is increased suddenly in a high-temperature combustion atmosphere higher than 1,500 deg.C, however, the fuel is catalyzed and reacted under a temperature lower than 1,200 deg.C and the decomposed gas is burnt under comparatively low-temperature condition, therefore, the production of NOX may be restricted.
